Polysynaptic reflex arcs differ from monosynaptic reflex arcs in that the former have ________, which are not present in the latter.

Groups of neuron cell bodies in the dorsal root are called ________.

The ventral root of a spinal nerve transmits ________ information ________ the spinal cord.

A ten-year-old boy falls from a tree, but manages to slow his descent somewhat by grabbing onto limbs he passes on the way to the ground. When he finally lands, he experiences some soreness on the buttocks, but otherwise does not think he is hurt until he discovers that he cannot move his fingers easily or accurately. What structures have been damaged

Bowel and bladder control involve spinal reflex arcs that are located in the sacral region of the spinal cord. In both instances two sphincter muscles, an internal sphincter of smooth muscle and an external sphincter of skeletal muscle, control the passageway out of the body. How would a transection of the spinal cord at the L1 level affect an individual's bowel and urinary bladder control
